Police have arrested a man on a string of weapons possession charges following investigations in the Southern Highlands area.

Officers from the Camden Command were investigating the theft of a 1979 Holden Utility from a property at Tahmoor as well as an assault at the same address.

They were called to the same address yesterday after reports of the male occupant being intimidated.

As a result, police have arrested a 47 year old man in his car, allegedly seizing a knife, extendable baton and ammunition.

Later police executed a search warrant on a home at Pheasant's Nest where they located a 1979 Holden Ut, two pen-guns, five rifles, a baton, a set of knuckle dusters, railway detonators and various ammunition.
